Mainly a sentence, taken from Tang Shuo: "Where auspicious, no exchanges." It mainly refers to understanding your state of mind when you are full of enthusiasm.
The famous figure of this spell is said to be Ma Boyong, known as Prince Xiangrui. It is said that this man is very strange. People who come into contact with him often encounter bad luck. Even if you have a car accident with your friends, many of them are injured, with different degrees of severity. However, he has been unscathed many times, which is similar to the luck of the national treasure panda, so he is called Prince Xiangrui, while those who suffer disasters are called "lucky". It means luck. Even when friends mention his name, they have to say "auspicious royal" to escape. . Later, it gradually evolved into a skill that can summon bad luck as long as you say "good luck and immunity", so it is not easy to use. Once you export it, everyone present will repeat it to prevent it from being affected ... but due to the serious follow-up, many people who replied "passing by" before changed to "auspicious royal exemption" and were widely criticized.
